CURLlNG-IRON.

SPECIFICATION forming part of Letters Patent No. 404,128, dated May 28, 1889.

Application filed November 20, 1888. Serial No. 291,342. (No model.)

To all whom it may concern:

Be it known that I, GEORGE LEVERETT THOMPSON, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Curling- Irons; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to an improvement in curling-irons of that class embracing a cylindric metal mandrel and a handle attached to the same, by which it may be manipulated.

The invention embraces an improved construction in a curling-iron of the kind described, by which the heat is prevented from passing from the body of the mandrel to the handle when the mandrel is heated for use, while at the same time the article is made in a strong and economical manner and is given a smooth and neat finish.

The invention consists in the matters hereinafter described, and pointed out in the ap pended claims.

As shown in the accompanying drawings, Figure 1 is a side view of a curling-iron constructed in accordance with my invention. Fig. 2 is a central longitudinal section thereof. Fig. 3 is a transverse section taken upon line 3 3 of Fig. 1. Fig. 4 is a transverse section taken upon line 4 4 of Fig. 1.

As illustrated in the drawings, A is the m andrel, which is made solid and of metal and cylindric in form.

B is the handle, which is preferably made of wood, and A is a tube connecting the handle and mandrel. Said tube A is formed in one piece with the body of the mandrel, preferably by milling out the metal at one end of a solid rod, so as to leave only a thin shell of suflicient strength to afford the necessary rigid connection between the mandrel and handle. The integral mandrel and tubular connecting-piece may, however, be otherwise constructed, as found convenient or desirable in practice. The handle is provided with a cylindric projection, 19, adapted to fit within the tube A, thereby affording a cheap and simple means of connecting the parts. The

handle may be secured within the tube in any suitable or well-known manner, the means employed in the curler shown in the drawings consisting of inwardly-projecting points a a, formed by punching in or depressing the metal of the tubular part into the cylindric projection b of the handle.

The mandrel and tube A are desirably but not necessarily made smooth and cylindric upon their outer surfaces and of the same diameter throughout the entire length of the mandrel and tube.

As a further and separate improvement, I provide the tube A, made integral with the mandrel in the manner above described, with a plurality of holes or openings, a (1, adapted to allow a free circulation of air through the tube for the purpose of keeping the same cool, such holes also reducing the cross-sectional area of the tube, through which heat may be conducted to the handle.

0 is a clasp, which is pivotally connected with the mandrel by means of a pivot-rod, c, inserted through the tube A, and is provided with a handle, C,the clasp beingheld against the mandrel by a leaf-spring, 0 secured to the handle near its end and bearing upon the said tube A. The pivot c is inserted through the tube A, in order to prevent the saidpivot from becoming too highly heated, and the end of the spring C is arranged to bear upon said tube for the same reason. A similarly-constructed clasp is shown and described in a separate application, Serial N0.280,893, filed by me upon the 24th day of July, 1888.

The purpose of the tube A is to prevent the transmission of heat from the mandrel to the handle when the former is heated for curling the hair, it being entirely obvious that if the solid metal of the mandrel is extended into contact with the handle the latter is liable to become charred, or at least to become too warm to be comfortably held in the hand. In said prior application, Serial No. 280,893, a curling-iron is shown and claimed in which the mandrel is connected with the handle by aseparate tube attached at its opposite ends to the mandrel and handle. The making of the tube integral with the mandrel, as herein set forth, makes the exterior of the mandrel and tube smooth and without any joint, thereby giving a neat and smooth finish to the same Without increasing its cost, and at the same time avoiding a joint which is liable to get loose or break in the long-continued use of the curler.

I claim as my invention-- 1. As a novel article, a curling-iron consisting of a cylindric mandrel, a handle, and a tube connecting the same, said tube forming a continuation of and being made of the same external diameter as and integral with the mandrel, and provided with a plurality of perforations, substantially as described.

2. As a novel article, a curling-iron consist- GEORGE LEVERETT THOMPSON,
